In 2028, a meteorite code-named "Eden" crashed into the Pacific Ocean, releasing unknown radiation that triggered a global genetic mutation three months later - animals and plants evolved wildly, and some humans mutated into "aberrants." At the same time, space cracks appeared in many places on the earth, connecting to an alien plane called the "Abyss", from which a large number of monsters poured out. Civilization collapsed within 72 hours.
